This commit adds suspend/resume support for the gatable clock driver
used on Marvell EBU platforms. When getting out of suspend, the
Marvell EBU platforms go through the bootloader, which re-enables all
gatable clocks. However, upon resume, the clock framework will not
disable again all gatable clocks that are not used.
Therefore, if the clock driver does not save/restore the state of the
gatable clocks, all gatable clocks that are not claimed by any device
driver will remain enabled after a resume. This is why this driver
saves and restores the state of those clocks.
Since clocks aren't real devices, we don't have the normal ->suspend()
and ->resume() of the device model, and have to use the ->suspend()
and ->resume() hooks of the syscore_ops mechanism. This mechanism has
the unfortunate idea of not providing a way of passing private data,
which requires us to change the driver to make the assumption that
there is only once instance of the gatable clock control structure.

On Marvell EBU platforms, when doing suspend/resume, the SDRAM window
configuration must be saved on suspend, and restored on
resume. However, it needs to be restored on resume *before*
re-entering the kernel, because the SDRAM window configuration defines
the layout of the memory. For this reason, it cannot simply be done in
the ->suspend() and ->resume() hooks of the mvebu-mbus driver.
Instead, it needs to be restored by the bootloader "boot info"
mechanism used when resuming. This mechanism allows the kernel to
define a list of (address, value) pairs when suspending, that the
bootloader will restore on resume before jumping back into the kernel.
This commit therefore adds a new function to the mvebu-mbus driver,
called mvebu_mbus_save_cpu_target(), which will be called by the
platform code to make the mvebu-mbus driver save the SDRAM window
configuration in a way that can be understood by the bootloader "boot
info" mechanism.

This commit extends the mvebu-mbus driver to provide suspend/resume
support. Since mvebu-mbus is not a platform_driver, the syscore_ops
mechanism is used to get ->suspend() and ->resume() hooks called into
the driver.
In those hooks, we save and restore the MBus windows state, to make
sure after resume all Mbus windows are properly restored. Note that
while the state of some windows could be gathered by looking again at
the Device Tree (for statically described windows), it is not the case
of dynamically described windows such as the PCIe memory and I/O
windows. Therefore, we take the simple approach of saving and
restoring the registers for all MBus windows.
In addition, the commit extends the Device Tree binding of the MBus
controller, to control the MBus bridge registers (which define which
parts of the physical address space is routed to MBus windows
vs. normal RAM memory). Those registers must be saved and restored
during suspend/resume. The Device Tree binding extension is made is a
backward compatible fashion, but of course, suspend/resume will not
work without the Device Tree update.

This commit adds suspend/resume support to the irqchip driver used on
Armada XP platforms (amongst others). It does so by adding a set of
suspend/resume syscore_ops, that will respectively save and restore
the necessary registers to ensure interrupts continue to work after
resume.
It is worth mentioning that the affinity is lost during a
suspend/resume cycle, because when a secondary CPU is brought
off-line, all interrupts that are assigned to this CPU in terms of
affinity gets re-assigned to a still running CPU. Therefore, right
before entering suspend, all interrupts are assigned to the boot CPU.

git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into omap-for-v3.19/soc
Some OMAP clock/hwmod patches for v3.19.
Most of the patches are clock-related. The DPLL implementation is
changed to better align to the common clock framework.
There is also a patch that removes a few lines from the hwmod code -
this patch should have no functional effect.
Basic build, boot, and PM test logs for these patches can be found here:
http://www.pwsan.com/omap/testlogs/omap-a-for-v3.19/20141113094101/
|

Currently, DPLLs are hiding the gory details of switching parent
within set_rate, which confuses the common clock code and is wrong.
Fixed by applying the new determine_rate() and set_rate_and_parent()
functionality to any clock-ops previously using the broken approach.
This patch also removes the broken legacy code.

Pull MTD fixes from Brian Norris:
"Three main MTD fixes for 3.18:
- A regression from 3.16 which was noticed in 3.17. With the
restructuring of the m25p80.c driver and the SPI NOR library
framework, we omitted proper listing of the SPI device IDs. This
means m25p80.c wouldn't auto-load (modprobe) properly when built as
a module. For now, we duplicate the device IDs into both modules.
- The OMAP / ELM modules were depending on an implicit link ordering.
Use deferred probing so that the new link order (in 3.18-rc) can
still allow for successful probing.

failing resume from hibernation and a cpufreq-dt driver issue related
to operation performance points.
Specifics:
- Fix a crash on r8a7791/koelsch during resume from system suspend
caused by a recent cpufreq-dt commit (Geert Uytterhoeven).
- Fix an MFD enumeration problem introduced by a recent commit adding
ACPI support to the MFD subsystem that exposed a weakness in the
ACPI core causing ACPI enumeration to be applied to all devices
associated with one ACPI companion object, although it should be
used for one of them only (Mika Westerberg).
- Fix an ACPI EC regression introduced during the 3.17 cycle causing
some Samsung laptops to misbehave as a result of a workaround
targeted at some Acer machines. That includes a revert of a commit
that went too far and a quirk for the Acer machines in question.
From Lv Zheng.
- Fix a regression in the system suspend error code path introduced
during the 3.15 cycle that causes it to fail to take errors from
asychronous execution of "late" suspend callbacks into account
(Imre Deak).
- Fix a long-standing bug in the hibernation resume error code path
that fails to roll back everything correcty on "freeze" callback
errors and leaves some devices in a "suspended" state causing more
breakage to happen subsequently (Imre Deak).
- Make the cpufreq-dt driver disable operation performance points
that are not supported by the VR connected to the CPU voltage plane
with acceptable tolerance instead of constantly failing voltage
scaling later on (Lucas Stach)"

Pull PCI fixes from Bjorn Helgaas:
"These changes, intended for v3.18, fix:
Sysfs
- Fix "enable" filename change (Greg Kroah-Hartman)
An unintentional sysfs filename change in commit 5136b2da770d
("PCI: convert bus code to use dev_groups"), which appeared in
v3.13, changed "enable" to "enabled", and this changes it back.
Old users of "enable" are currently broken and will be helped by
this change. Anything that started to use "enabled" after v3.13
will be broken by this change. If necessary, we can add a symlink
to make both work, but this patch doesn't do that.
PCI device hotplug

A mistaken duplicate merge that added a check twice. Nothing's
broken; this just removes the unnecessary code.

Pull sparc update from David Miller:
"Two changes:
1) It makes no sense to execute a VTOC partition table request in the
Sun virtual block device driver and fail to load if it doesn't
succeed because a) we don't use the result at all and b) it won't
succeed if there is an EFI partition on the disk, for example.
We read the partition table via the normal means in the block layer
anyways, so this is really completely useless, so just remove it.

The cpsw driver did not support the IFF_ALLMULTI flag which makes dynamic
multicast routing not work. Related to this, when enabling IFF_PROMISC
in switch mode, all registered multicast addresses are flushed, resulting
in only broadcast and unicast traffic being received.
A new cpsw_ale_set_allmulti function now scans through the ALE entry
table and adds/removes the host port from the unregistered multicast
port mask of each vlan entry depending on the state of IFF_ALLMULTI.
In promiscious mode, cpsw_ale_set_allmulti is used to force reception
of all multicast traffic in addition to the unicast and broadcast traffic.
With this change dynamic multicast and promiscious mode both work in
switch mode.

0d961b3b52f566f823070ce2366511a7f64b928c (drivers: net: cpsw: fix buggy
loop condition) accidentally fixed a loop comparison in too many places
while fixing a real bug.
It was correct to fix the dual_emac mode section since there 'i' is used
as an index into priv->slaves which is a 0 based array.
However the other two changes (which are only used in switch mode)
are wrong since there 'i' is actually the ALE port number, and port 0
is the host port, while port 1 and up are the slave ports.
Putting the loop condition back in the switch mode section fixes it.
A comment has been added to point out the intent clearly to avoid future
confusion. Also a comment is fixed that said the opposite of what was
actually happening.

With legacy booting, the platform init code was taking care of
the configuring of GPIOs. With device tree based booting, things
may or may not work depending what bootloader has configured or
if the legacy platform code gets called.
Let's add support for the pwrdn and reset GPIOs to the smc91x
driver to fix the issues of smc91x not working properly when
booted in device tree mode.
And let's change n900 to use these settings as some versions
of the bootloader do not configure things properly causing
errors.

The VD_OP_GET_VTOC operation will succeed only if the vdisk backend has a
VTOC label, otherwise it will fail. In particular, it will return error
48 (ENOTSUP) if the disk has an EFI label. VTOC disk labels are already
handled by directly reading the disk in block/partitions/sun.c (enabled by
CONFIG_SUN_PARTITION which defaults to y on SPARC). Since port->label is
unused in the driver, remove the call and the field.

For Renesas USB 3.0 host controller, when unplugging the usb hub which
has the RTL8153 plugged, the driver would get -EPROTO for interrupt
transfer. There is high probability to get the information of "HC died;
cleaning up", if the driver continues to submit the interrupt transfer
before the disconnect() is called.

This reverts commit 68da166491655bc54051bf04c78ce648e2e33508.
It turns out that the assertion about scope of regressions due to
always keeping keyboard controller in legacy mode was proven wrong.
There are laptops, such as Clevo W650SH, that only have internal
touchpad (no external PS/2 ports), that require active multiplexing
mode to switch the touchpad (Elantech) into native mode instead of
basic PS/2 emulation.
